Italian luxury sports car maker Maserati has declared its interest in rejoining motorsport. It’s done so in emphatic fashion by trickling details of the upcoming MC20 super-sportscar, and now the company has released details of the engine, called “Nettuno”, that will be the heartbeat of the machine.It’s got some real oomph; capacity is 3.0L, in a 90 degree twin-turbo V6 configuration. The dry-sumped design provides a peak power figure of 463kW and torque of 730Nm. 7,500rpm is where the power comes in whilst torque is at a very useable 3,000rpm. It’s close to a square-bore design too, with bore and stroke 88mm x 82mm. It will run a 11:1 compression ratio. Looking to Formula 1, Maserati have employed the use of a pre-chamber combustion system featuring twin-spark plugs. This will mark the first time this kind of technology will be provided for a road-going vehicle.Three features define the MC20’s engine. The pre-chamber is located between the “normal” combustion chamber and the electrode of the ignition system. A set of specially engineered holes connect the two sections. A traditional sparkplug is utilised as a backup to to the new ignition system, and is designed to make sure combustion is ongoing when load is such the pre-chamber’s services are not required. The final step is an innovative fuel injection system, with a direct and indirect system lowering consumption and emissions whilst ensuring fuel is appropriate across the rev range.
Lateral sparkplug: a traditional sparkplug acts as a support to ensure constant combustion when the engine is operating at a level that doesn’t need the pre-chamber to kick in. Twin injection system – direct and indirect: linked to the fuel supply pressure at 350bar, the system reduces noise low down on the rev range, lowering emissions and improving consumption.The MC20 itself will make its world debut proper in September and will showcase the work done at Maserati’s Modena HQ division There is the Maserati’s Modena facilities: the Maserati Innovation Lab on Via Emilia Ovest, the workshops on Via Delle Nazioni and developed at the Engine Hub, situated at the famous Viale Ciro Menotti address where it will be built. Currently the new production line and new paint shop are being modified to host the much-anticipated MC20. MC20 means Maserati Corse 2020.
